BACKGROUND

The circadian clock is an intrinsic time-keeping mechanism that controls the daily rhythms of many physiological processes, such as sleep/wake behavior, body temperature, hormone secretion, and metabolism (Takahashi, J. S. et al. Nat. Rev. Genet. 2008, 9, 764; Green, C. B. et al. Cell, 2008, 134, 728; Zhang, E. E. et al. Nat. Rev. Mol. Cell. Biol. 2010, 11, 764). Circadian rhythms are generated in a cell-autonomous manner through transcriptional regulatory networks of clock genes. In the core feedback loop, the transcription factors CLOCK and BMAL1 activate expression of Period (Per1 and Per2) and Cryptochrome (Cry1 and Cry2) genes. After translation and nuclear localization, PER and CRY proteins inhibit the function of CLOCK-BMAL1, resulting in sustained rhythmic gene expression. Many physiological pathways are under the control of the circadian clock (Panda, S. et al. Cell, 2002, 109, 307), including direct regulation of numerous hepatic processes (Rey, G. et al. PLoS Biol. 2011, 9, e1000595; Bugge, A. et al. Genes Dev. 2012, 26, 657).

Circadian desynchrony has been associated with impaired insulin sensitivity (Spiegel, K. et al. J. Appl. Physiol. 2005, 99, 2008; Spiegel, K. et al. Lancet, 1999, 354, 1435), decreased leptin levels and results in hyperglycemia, hyperinsulinemia and postprandial glucose responses comparable to those of a prediabetic state (Scheer, F. A. et al. Proc. Natl. Acad. Sci. USA, 2009, 106, 4453). Several genome-wide association studies led to the discovery that Cry2 may be important in the regulation of mammalian glucose levels (Dupuis, J. et al. Nat. Genet. 2010, 42, 105; Liu, C. et al. PLoS One, 2011, 6, e21464; Barker, A. et al. Diabetes, 2011, 60, 1805).

Glucose concentrations in the blood are highly rhythmic because of changes in insulin sensitivity and insulin secretory capacity of the endocrine pancreas (Polonsky, K. S. et al. N. Engl. J. Med. 1988, 318, 1231). Clock^(Δ19) mutant mice develop age-dependent hyperglycemia and these animals also develop susceptibility to diet-induced obesity, have inappropriately low concentrations of insulin (Turek, F. W. et al. Science, 2005, 308, 1043) and display a steeper drop in blood sugar in response to treatment with insulin, indicating that these animals have enhanced insulin sensitivity, thereby masking their β-cell deficiency (Marcheva, B. et al. Nature, 2010, 466, 627). Liver-specific deletion of Bmal1 in mice results in impaired glucose tolerance and increased insulin sensitivity (Lamia, K. A. et al. Proc. Natl. Acad. Sci. USA, 2008, 105, 15172). Individuals with type 2 diabetes, and even their first-degree relatives not yet affected with the disease, display altered rhythmicity in glucose tolerance (Boden, G. et al. Diabetes, 1999, 48, 2182). Also, Per2, Per3, and Cry2 expression is significantly lower in humans with type 2 diabetes versus humans without the disease (Stamenkovich, J. A. et al. Metabolism, 2012, 61, 978). The gluconeogenic genes phosphoenol pyruvate carboxykinase (Pck1) and glucose 6-phosphatase (G6pc) are controlled by CRY and the Bmal1 gene regulator REV-ERB (Zhang, E. E. et al. Nat. Med. 2010, 16, 1152; Lamia, K. A. et al. Nature, 2011, 480, 552; Yin, L. et al. Science, 2007, 318, 1786). Gluconeogenesis is tightly controlled by multiple signaling mechanisms and moreover, studies in mice have revealed that modulation of Cry1 and Cry2 can perturb gluconeogenesis and regulate blood sugar levels (Zhang, E. E. et al. Nat. Med. 2010, 16, 1152).

In a monotherapeutic or combination therapy context, new and established oral antidiabetic agents have non-uniform and limited effectiveness. Oral antidiabetic therapies suffer from poor or limited glycemic control, or poor patient compliance due to unacceptable side effects, such as edema, weight gain, or even more serious complications like hypoglycemia. Metformin, a substituted biguanide, can cause diarrhea and gastrointestinal discomfort. Finally, edema, weight gain, and in some cases, hepatotoxicity and cardiotoxicity, have been linked to the administration of some thiazolidine-2,4-dione antidiabetic agents (e.g. Rosiglitazone and Pioglitazone). Combination therapy using two or more of the above agents is common, but generally only leads to incremental improvements in glycemic control.

Cry1 and Cry2 also interact with the glucocorticoid receptor (GR) to globally alter the transcriptional response to glucocorticoids (Lamia, K. A. et al. Nature, 2011, 480, 552). Loss of Cry1 and/or Cry2 results in glucose intolerance and constitutively high levels of circulating corticosterone, suggesting reduced suppression of the hypothalamic-pituitary-adrenal axis coupled with increased glucocorticoid transactivation in the liver. Genomically, Cry1 and Cry2 associate with a glucocorticoid response element in the Pck1 promoter in a hormone-dependent manner, and dexamethasone-induced transcription of the Pck1 gene was strikingly increased in cryptochrome-deficient livers. This suggests that the undesirable metabolic side effects of glucocorticoids (e.g. hyperglycemia, insulin resistance and suppression of adrenal function) used to suppress inflammation may be alleviated by combining them with agents that can stabilize Cry1 and/or Cry2.

The term “pharmaceutically acceptable” as used herein, refers to a material, such as a carrier or diluent, which does not abrogate the biological activity or properties of the compounds described herein, and is relatively nontoxic, i.e., the material may be administered to an individual without causing undesirable biological effects or interacting in a deleterious manner with any of the components of the composition in which it is contained.

The term “pharmaceutically acceptable salt” as used herein, refers to salts that retain the biological effectiveness of the free acids and bases of the specified compound and that are not biologically or otherwise undesirable. Pharmaceutically acceptable salts of the compounds of formula I include the acid addition and base salts thereof. Suitable acid addition salts are formed from acids which form non-toxic salts. Examples include acetate, adipate, arabogalactanesulfonate, ascorbate, aspartate, benzoate, besylate, bicarbonate/carbonate, bisulfate/sulfate, borate, camsylate, cholate, citrate, edisylate, estolate, esylate, formate, fumarate, galacturonate, gluceptate, gluconate, glucuronate, glutamate, hexafluorophosphate, hibenzate, hippurate, hydrochloride/chloride, hydrobromide/bromide, hydroiodide/iodide, 3-hydroxy-2-naphthoate, 1-hydroxy-2-naphthoate, isethionate, lactate, lactobionate, malate, maleate, malonate, mandelate, mesylate, methylsulfate, mucate, napadisylate, naphthalate, 2-napsylate, nicotinate, nitrate, oleate, orotate, oxalate, palmitate, pamoate, phosphate/hydrogen phosphate/dihydrogen phosphate, saccharate, salicylate, stearate, succinate, sulfosalicylate, tartrate, tosylate, trifluoroacetate, and tryptophanate salts.

For a review on suitable salts, see “Handbook of Pharmaceutical Salts: Properties, Selection, and Use” by Stahl and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).

A pharmaceutically acceptable salt of a compound of formula I may be readily prepared by mixing together solutions of the compound of formula I and the desired acid or base, as appropriate. The salt may precipitate from solution and be collected by filtration or may be recovered by evaporation of the solvent. The degree of ionization in the salt may vary from completely ionized to almost non-ionized.

The compounds of Formula I may also exist in various crystalline forms, known as polymorphs. Polymorphs include the different crystal packing arrangements of the same elemental composition of a compound. Polymorphs may have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, solvates and solubility. Various factors such as the recrystallization solvent, rate of crystallization, and storage temperature may cause a single crystal form to dominate.

A “solvate” is intended to mean a pharmaceutically acceptable solvate form of a specified compound that retains the biological effectiveness of such compound. Examples of solvates include compounds of the invention in combination with water, isopropanol, ethanol, methanol, dimethylsulfoxide, ethyl acetate, acetic acid, or ethanolamine. The term “hydrate” refers to a solvate where the solvent is water. The term “alcoholate” refers to a solvate where the solvent is an alcohol. Hydrates are formed by the combination of one or more molecules of water with one molecule of the substance in which the water retains its molecular state as H₂O. Non-limiting examples of hydrates include monohydrates, dihydrates, etc.

The compounds of the invention include compounds of formula I as defined herein, polymorphs, prodrugs, and isomers, thereof (including optical, geometric, and tautomeric isomers) as well as isotopically-labeled compounds of formula I.

The compounds of the present invention may be administered as prodrugs. Thus certain derivatives of compounds of formula I which may have little or no pharmacological activity themselves can, when administered into or onto the body, be converted into compounds of formula I having the desired activity, for example, by hydrolytic cleavage. Such derivatives are referred to as ‘prodrugs’. Further information on the use of prodrugs may be found in “Pro-drugs as Novel Delivery Systems, Vol. 14, ACS Symposium Series (T. Higuchi and W. Stella) and “Bioreversible Carriers in Drug Design”, Pergamon Press, 1987 (Ed. E. B. Roche, American Pharmaceutical Association). Prodrugs can, for example, be produced by replacing appropriate functionalities present in the compounds of formula I with certain moieties known to those skilled in the art is ‘pro-moieties’ as described, for example, in “Design of Prodrugs” by H. Bundgaard (Elsevier, 1985).

Some examples of such prodrugs include where the compound of formula I contains a carboxylic acid functionality (—CO₂H), an ester thereof, for example, replacement of the hydrogen with (C₁-C₈)alkyl; where the compound of formula I contains an alcohol functionality (—OH), an ether thereof, for example, replacement of the hydrogen with (C₁-C₈)alkanoyloxymethyl; and where the compound of formula I contains a secondary amino functionality (—NHR where R is not H), an amide thereof, for example, replacement of one hydrogen with (C₁-C₁₀)alkanoyl. Further examples of replacement groups in accordance with the foregoing examples and examples of other prodrug types are known to those of ordinary skill in the art.

Compounds of formula I contain one or more asymmetric carbon atoms. It is to be understood that all the enantiomers and/or diastereomers corresponding to the compounds of formula I can be prepared by analogous methods. All optical isomers and stereoisomers of the compounds of formula I, and mixtures thereof, are considered to be within the scope of the invention. With respect to the compounds of formula I, the invention includes the use of a racemate, one or more enantiomeric forms, one or more diastereomeric forms, or mixtures thereof. The compounds of formula I may also exist as tautomers. This invention relates to the use of all such tautomers and mixtures thereof.

Certain functional groups contained within the compounds of the present invention can be substituted for bioisosteric groups, that is, groups which have similar spatial or electronic requirements to the parent group, but exhibit differing or improved physicochemical or other properties. Suitable examples are well known to those of skill in the art, and include, but are not limited to moieties described in Patini, et al. Chem Rev. 1996, 96, 3147-3176 and references cited therein.

Included within the scope of the claimed compounds of formula I are pharmaceutically acceptable acid addition or base salts wherein the counterion is optically active, for example, D-lactate or L-lysine, or racemic, for example, DL-tartrate or DL-arginine. Cis/trans isomers may be separated by conventional techniques well known to those skilled in the art, for example, chromatography and fractional crystallization. Conventional techniques for the preparation/isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate (or the racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC).

Alternatively, the racemate (or a racemic precursor) may be reacted with a suitable optically active compound, for example, an alcohol, or, in the case where the compound of formula I contains an acidic or basic moiety, an acid or base such as tartaric acid or 1-phenylethylamine. The resulting diastereomeric mixture may be separated by chromatography and/or fractional crystallization and the diastereomers converted to the corresponding pure enantiomers and/or diastereomers by means well known to a skilled person. The chiral compounds of the invention (and chiral precursors thereof) may be obtained in enantiomerically- and/or diastereomerically-enriched form using chromatography, typically HPLC, on an asymmetric resin with a mobile phase consisting of a hydrocarbon, typically heptane or hexane, containing from 0 to 50% isopropanol, typically 2 to 20%, and from 0 to 5% of an alkylamine, typically 0.1% diethylamine. Concentration of the eluate affords the enriched mixture. Mixtures of enantiomers and/or diastereomers may be separated by conventional techniques known to those skilled in the art. See, for example, “Stereochemistry of Organic Compounds” by E. L. Eliel (Wiley, New York, 1994).

The compounds of formula I may be isotopically-labeled, wherein one or more atoms are replaced by atoms having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes suitable for inclusion in the compounds of the invention include isotopes of hydrogen, such as ²H and ³H, carbon, such as ¹¹C, ¹³C and ¹⁴C, chlorine, such as ³⁶Cl, fluorine, such as ¹⁸F, iodine, such as ¹²³I and ¹²⁵I, nitrogen, such as ¹³N and ¹⁵N, oxygen, such as ¹⁵O, ¹⁷O and ¹⁸O, phosphorous, such as ³²P, and sulfur, such as ³⁵S. Certain isotopically-labeled compounds of formula I, for example, those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e. ³H, and carbon-14, i.e. ¹⁴C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Substitution with heavier isotopes such as deuterium, i.e. ²H, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Substitution with positron emitting isotopes, such as ¹¹C, ¹⁸F, ¹⁵O and ¹³N, can be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy. Isotopically-labeled compounds of formula I can be generally prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples and Preparations using appropriate isotopically-labeled reagents in place of the non-labeled reagent previously employed.

The compounds of the present invention modulate Cry1 and/or Cry2. As used herein, “modulating” refers to increasing, decreasing, or altering Cry1 and Cry2 function, activity or intrinsic characteristics. Modulation of Cry1 or Cry2 includes any one of the following: binding to Cry1 or Cry2; inhibiting modification of Cry1 or Cry2; altering Cry1 or Cry2 localization; increasing or decreasing Cry1 or Cry2 stabilization; increasing or decreasing the binding between Cry1 or Cry2 to a target; increasing or decreasing Cry1 or Cry2 activity; and increasing or decreasing activity of a Cry1 or Cry2 target, or any combination thereof. Targets of Cry1 and/or Cry2 include, but are not limited to, Per1, Per2, glucocorticoid receptor (GR), CLOCK, BMAL1, or a CLOCK-BMAL1 promoter sequence.

Modulation of Cry1 and Cry2 includes: binding of a compound of the present invention to Cry1 and/or Cry2, either through direct interaction or indirect interaction. In some aspects, a compound of the present invention may bind to a complex containing Cry1 and/or Cry2. Methods for detecting interaction between small molecules and proteins are known in the art, for example, immunoprecipitation techniques, chromatography, and various array formats.

Intrinsic characteristics of Cry1 and Cry2, such as post-translational modification, stability, or localization, may be altered by the compounds of the present invention. Post-translational modification of Cry1 and Cry2 may play a critical role in determining the activity, stability, or cellular localization of Cry1 and Cry2. Some studies have shown that phosphorylation may alter Cry1 and Cry2 stability. Compounds of the present invention may prevent or increase post-translational modification of Cry1 and Cry2, for example, phosphorylation, ubiquitination, acetylation, glycosylation, ribosylation, or sumoylation. Methods for detecting post-translational modification of Cry1 or Cry2 can be readily performed by one skilled in the art. Such methods of detection include western blot and radioimmunoassays. Cry1 and Cry2 localize to the nucleus under particular conditions, for example, upon heterodimerization with Per1 and Per2. Once within the nucleus, Cry1 and Cry2 play a role in disrupting the nuclear CLOCK-BMAL1 complex from initiating transcription, thereby downregulating circadian rhythm genes in a negative feedback loop that is crucial for maintaining circadian oscillations. Localization of proteins can be readily determined by one in the art, for example, by immunofluorescence, subcellular fractionation and western blot assays. Downregulation of Cry1 and Cry2 is also critical for circadian oscillations, and is mediated at the transcriptional and protein level. Cry1 and Cry2 stability can be measured by methods known in the art, as well as those presented in Examples 5-8.

Cry1 and Cry2 activity, as used herein, includes the binding between Cry1 or Cry2 to a target and the activity of a downstream Cry1 or Cry2 target. Compounds of the present invention may increase or decrease the binding between Cry1 or Cry2 to a target. Targets that bind to Cry1 and/or Cry2 are known in the art, and include Per1, Per2, glucocorticoid receptor, the CLOCK-BMAL1 promoter sequence, and the VEGF promoter sequence. Cry1 and Cry2 targets referenced herein also include those targets that have yet to be identified. Binding between Cry1 or Cry2 and targets can be determined by, for example, immunoprecipitation, yeast two-hybrid, affinity chromatography. Downstream activity of Cry1 or Cry2 targets comprises CLOCK-BMAL1-mediated transcription, binding of Cry1 or Cry2 to the CLOCK-BMAL-1 promoter, binding of Cry1 or Cry2 to the VEGF promoter, Per1 or Per2 localization or stability, CLOCK-BMAL1 dimerization, expression of CLOCK-BMAL1 target genes, such as Cry1, Cry2, Per1, Per2, Rev-erb □ and □, Rora, TIM proteins, and VEGF. Methods for detecting promoter activity can be determined by chromatin immunoprecipitation, electrophoretic mobility shift assay, or promoter-luciferase assays as described in Examples 3 and 4. Methods for determining expression of target genes include gene expression analysis and microarrays, which can be readily performed by one ordinarily skilled in the art.

In other aspects of the subject matter disclosed herein, a pharmaceutical composition is provided, comprising the compound according to formula I and a pharmaceutically acceptable carrier, adjuvant or diluent. Methods of preparing various pharmaceutical compositions with a specific amount of active compound are known, or will be apparent, to those skilled in the art. In addition, those of ordinary skill in the art are familiar with formulation and administration techniques. Such topics will be discussed, e.g. in Goodman and Gilman's “The Pharmaceutical Basis of Therapeutics”, current edition, Pergamon Press; and “Remington's Pharmaceutical Sciences”, current edition, Mack Publishing, Co., Easton, Pa. These techniques can be employed in appropriate aspects and embodiments of the methods and compositions described herein. Pharmaceutical compositions are preferably manufactured under GMP conditions. The following examples are provided for illustrative purposes only and are not meant to serve as limitations of the present invention.

Percentages as provided herein are on a weight for weight basis. Impure preparations of the compounds may be used for preparing the more pure forms used in the pharmaceutical compositions; these less pure preparations of the compounds should contain at least 1%, more suitably at least 5%, e.g. 10 to 49% of a compound of the Formula I.

The compounds of formula I may be provided in suitable topical, oral, nasal, ocular, mucosal, rectal, vaginal, and parenteral pharmaceutical formulations for use in the treatment of Cry mediated diseases. The compounds of the present invention may be administered orally as tablets or capsules, as oily or aqueous suspensions, lozenges, troches, powders, granules, emulsions, syrups or elixirs. The compositions for oral use may include one or more agents for flavoring, sweetening, coloring and preserving in order to produce pharmaceutically elegant and palatable preparations. Tablets may contain pharmaceutically acceptable excipients, carriers, diluents, and adjuvants as an aid in the manufacture of such tablets. As is conventional in the art, these tablets may be coated with a pharmaceutically acceptable enteric coating, such as glyceryl monostearate or glyceryl distearate, to delay disintegration and absorption in the gastrointestinal tract to provide a sustained action over a longer period. The dissolution rate of poorly water-soluble compounds may be enhances by the use of spray-dried dispersion, such as those described by Takeuchi, H. et al. J. Pharm. Pharmacol. 1987, 39, 769-773.

Formulations for oral use may be in the form of hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin. They may also be in the form of soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, such as peanut oil, liquid paraffin or olive oil.

Aqueous suspensions normally contain active ingredients in admixture with excipients suitable for the manufacture of an aqueous suspension. Such excipients many be a suspending agent, such as Kolliphor, sodium carboxymethyl cellulose, methyl cellulose, hydroxypropylmethyl cellulose, sodium alginate, polyvinylpyrrolidone, gum tragancanth and gum acacia; a dispersing or wetting agent that may be a naturally occurring phosphatide such as lecithin, a condensation product of ethylene oxide and a long chain fatty acid, for example polyoxyethylene stearate, a condensation product of ethylene oxide and a long chain aliphatic alcohol such as heptadecaethyleneoxycetanol, a condensation product of ethylene oxide and a partial ester derived from a fatty acid and hexitol such as polyoxyethylene sorbitol monooleate or a fatty acid hexitol anhydrides such as polyoxyethylene sorbitan monooleate.

The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to known methods as aqueous isotonic solutions or suspensions, and suppositories can be prepared from fatty emulsions or suspensions. The compositions can be sterilized and/or contain adjuvants, such as preserving, stabilizing, wetting or emulsifying agents, solution promoters, salts for regulating the osmotic pressure and/or buffers. In addition, they can also contain other therapeutically valuable substances. The sterile injectable preparation may also be formulated as a suspension in a non-toxin parenterally-acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringers solution and isotonic sodium chloride solution. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition fatty acids such as oleic acid find use in the preparation of injectables.

The compounds of formula I may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient that is solid at about 25° C., but liquid at rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and other glycerides.

For topical or transdermal use preparations, for example, creams, ointments, jellies solutions or suspensions containing the compounds of the present invention are employed. Suitable formulations for transdermal applications include an effective amount of a compound of the present invention with a carrier. A carrier can include absorbable pharmacologically acceptable solvents to assist passage through the skin of the host. For example, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the compound to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin. Matrix transdermal formulations and iontophoresis devices can also be used. Suitable formulations for topical application, e.g., to the skin and eyes, are preferably aqueous solutions, ointments, creams or gels well-known in the art. Such can contain solubilizers, stabilizers, tonicity enhancing agents, buffers and preservatives.

The active compounds can be prepared with pharmaceutically acceptable carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art.

The compounds of formula I may also be prepared in the form of liposome delivery systems such as small unilamellar vesicles, large unilamellar vesicles and multimellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine or phosphatidylcholines.

Suitable extended release form of the either active pharmaceutical ingredient or both may be a matrix tablet or capsule composition. Suitable matrix forming materials include, for example, waxes (e.g., carnauba, bees wax, paraffin wax, ceresine, shellac wax, fatty acids, and fatty alcohols), oils, hardened oils or fats (e.g., hardened rapeseed oil, castor oil, beef tallow, palm oil, and soya bean oil), and polymers (e.g., hydroxypropyl cellulose, polyvinylpyrrolidone, hydroxypropyl methyl cellulose, and polyethylene glycol). Other suitable matrix tabletting materials are microcrystalline cellulose, powdered cellulose, hydroxypropyl cellulose, ethyl cellulose, with other carriers, and fillers. Tablets may also contain granulates, coated powders, or pellets. Tablets may also be multi-layered. Multi-layered tablets are especially preferred when the active ingredients have markedly different pharmacokinetic profiles. Optionally, the finished tablet may be coated or uncoated.

The coating composition typically contains an insoluble matrix polymer (approximately 15-85% by weight of the coating composition) and a water soluble material (e.g., approximately 15-85% by weight of the coating composition). Optionally an enteric polymer (approximately 1 to 99% by weight of the coating composition) may be used or included. Suitable water soluble materials include polymers such as polyethylene glycol, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, polyvinylpyrrolidone, polyvinyl alcohol, and monomeric materials such as sugars (e.g., lactose, sucrose, fructose, mannitol and the like), salts (e.g., sodium chloride, potassium chloride and the like), organic acids (e.g., fumaric acid, succinic acid, lactic acid, and tartaric acid), and mixtures thereof. Suitable enteric polymers include hydroxypropyl methyl cellulose, acetate succinate, hydroxypropyl methyl cellulose, phthalate, polyvinyl acetate phthalate, cellulose acetate phthalate, cellulose acetate trimellitate, shellac, zein, and polymethacrylates containing carboxyl groups.

The coating composition may be plasticised according to the properties of the coating blend such as the glass transition temperature of the main component or mixture of components or the solvent used for applying the coating compositions. Suitable plasticisers may be added from 0 to 50% by weight of the coating composition and include, for example, diethyl phthalate, citrate esters, polyethylene glycol, glycerol, acetylated glycerides, acetylated citrate esters, dibutylsebacate, and castor oil. If desired, the coating composition may include a filler. The amount of the filler may be 1% to approximately 99% by weight based on the total weight of the coating composition and may be an insoluble material such as silicon dioxide, titanium dioxide, talc, kaolin, alumina, starch, powdered cellulose, MCC, or polacrilin potassium. The coating composition may be applied as a solution or latex in organic solvents or aqueous solvents or mixtures thereof. If solutions are applied, the solvent may be present in amounts from approximate by 25-99% by weight based on the total weight of dissolved solids. Suitable solvents are water, lower alcohol, lower chlorinated hydrocarbons, ketones, or mixtures thereof. If latexes are applied, the solvent is present in amounts from approximately 25-97% by weight based on the quantity of polymeric material in the latex. The solvent may be predominantly water. Dosage levels of the compounds of the present invention are of the order of about 0.5 mg/kg body weight to about 100 mg/kg body weight, or any increment in between. A preferred dosage rate is between about 30 mg/kg body weight to about 100 mg/kg body weight. The total daily dose may be administered in single or divided doses. Suitable therapeutic doses of the compounds of formula I may be in the range of 1 microgram (g) to 1000 milligrams (mg) per kilogram body weight of the recipient per day, and any increment in between, such as, e.g., 1, 2, 3, 5, 10, 25, 50, 75, 100, 200, 300, 400, 500, 600, 700, 800, 900, or 1000 g (1 mg); 2, 3, 5, 10, 25, 50, 75, 100, 200, 300, 400, 500, 600, 700, 800, 900 or 1000 mg. It will be understood, however, that specific dose level for any particular patient will depend upon a number of factors including the activity of the particular compound being administered, the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy.

Dosage regimens may be adjusted to provide the optimum desired response. For example, a single bolus may be administered, several divided doses may be administered over time or the dose may be proportionally reduced or increased as indicated by the exigencies of the therapeutic situation. It is especially advantageous to formulate parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form, as used herein, refers to physically discrete units suited as unitary dosages for mammalian subjects to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on (a) the unique characteristics of the therapeutic agent and the particular therapeutic or prophylactic effect to be achieved, and (b) the limitations inherent in the art of compounding such an active compound for the treatment of sensitivity in individuals. Thus, the skilled artisan would appreciate, based upon the disclosure provided herein, that the dose and dosing regimen is adjusted in accordance with methods well-known in the therapeutic arts. That is, the maximum tolerable dose can be readily established, and the effective amount providing a detectable therapeutic benefit to a patient may also be determined, as can be temporal requirements for administering each agent to provide a detectable therapeutic benefit to the patient. Accordingly, while certain dose and administration regimens are exemplified herein, these examples in no way limit the dose and administration regimen that may be provided to a patient in practicing the present invention.

The terms “administer,” “administering”, “administration,” and the like, as used herein, refer to the methods that may be used to enable delivery of compounds or compositions to the desired site of biological action. These methods include, but are not limited to oral, parenteral, topical, mucosal, ocular, ophthalmic, vaginal, and rectal administration. Those of skill in the art are familiar with administration techniques that can be employed with the compounds and methods described herein, e.g., as discussed in Goodman and Gilman, The Pharmacological Basis of Therapeutics, current ed.; Pergamon; and Remington's, Pharmaceutical Sciences (current edition), Mack Publishing Co., Easton, Pa. As used herein, “parenteral administration” of a pharmaceutical composition includes any route of administration characterized by physical breaching of a tissue of a subject and administration of the pharmaceutical composition through the breach of the tissue. Parenteral administration thus includes, but is not limited to, administration of a pharmaceutical composition by injection of the composition, by application of the composition through a surgical incision, by application of the composition through a tissue-penetrating non-surgical wound, and the like. In particular, parenteral administration is contemplated to include, but is not limited to, subcutaneous, intraperitoneal, intramuscular, and intrasternal injection, and kidney dialytic infusion techniques.

A “subject” in the context of the present invention is preferably a mammal. The mammal can be a human, non-human primate, mouse, rat, dog, cat, horse, or cow, but are not limited to these examples. Mammals other than humans can be advantageously used as subjects that represent animal models of a Cry-mediated disease or disorder, such as ob/ob mice. A subject can be male or female. A subject can be one who has been previously diagnosed or identified as having a Cry-mediated disease or disorder, and optionally has already undergone, or is undergoing, a therapeutic intervention or treatment for the disease or disorder. Alternatively, a subject can also be one who has not been previously diagnosed as having a Cry-mediated disease or disorder. For example, a subject can be one who exhibits one or more risk factors for a Cry-mediated disease or disorder, or a subject who does not exhibit risk factors for a Cry-mediated disease or disorder, or a subject who is asymptomatic for a Cry-mediated disease or disorder. A subject can also be one who is suffering from or at risk of developing a Cry-mediated disease or disorder, or who is suffering from or at risk of developing a recurrence of a Cry-mediated disease or disorder. A subject can also be one who has been previously treated for a Cry-mediated disease or disorder, whether by administration of the compounds and compositions disclosed herein, either alone or in combination with other therapeutic agents, surgery, or any combination of the foregoing.

A “Cry-mediated disease or disorder” may include, without limitation, diabetes (including, without limitation, insulin-dependent “Type I” diabetes, non-insulin dependent “Type II” diabetes, gestational diabetes, and diabetes-related complications like diabetic neuropathy, diabetic retinopathy, diabetic cardiomyopathy, diabetic nephropathy, periodontal disease, and diabetic ketoacidosis), metabolic syndrome, insulin resistance syndrome, obesity, glaucoma, Cushing's syndrome, psychotic depression, Alzheimer's disease, neuropathic pain, drug abuse, osteoporosis, cancer, macular degeneration, and myopathy.

The term “treating”, “treat”, or “treatment” as used herein includes preventative (e.g. prophylactic), palliative, adjuvant, and curative treatment. For example, the treatment of type 2 diabetes, as used herein means that a patient having type 2 diabetes or at risk of having type 2 diabetes can be treated according to the methods described herein. For patients undergoing preventative treatment, a resulting reduction in the incidence of the disease state being preventively treated is the measurable outcome of the preventative treatment.

The term “alleviating” or “alleviate” as used herein describes a process by which the severity of a sign or symptom of a disorder is decreased, reduced, or inhibited. Importantly, a symptom can be alleviated without being eliminated. In a preferred embodiment, the administration of pharmaceutical compositions of the invention leads to the elimination of a symptom, however, elimination is not required. Therapeutically effective amounts of the compounds or pharmaceutical compositions described herein are expected to decrease the severity of a symptom.

As used herein the term “symptom” is defined as an indication of disease, illness, injury, or that something is not right in the body. Symptoms are felt or noticed by the individual experiencing the symptom, but may not easily be noticed by others. Others are defined by health-care or clinical professionals.

The term “metabolic syndrome”, as used herein, unless otherwise indicated means psoriasis, diabetes mellitus, wound healing, inflammation, neurodegenerative diseases, galactosemia, maple syrup urine disease, phenylketonuria, hypersarcosinemia, thymine uraciluria, sulfinuria, isovaleric academia, saccharopurinuria, 4-hydroxybutyric aciduria, glucose-6-phosphate dehydrogenase deficiency, and pyruvate dehydrogenase deficiency.

The term “obesity” or “obese”, as used herein, refers generally to individuals who are at least about 20-30% over the average weight for his/her age, sex and height. Technically, “obese” is defined, for males, as individuals whose body mass index is greater than 27.8 kg/m², and for females, as individuals whose body mass index is greater than 27.3 kg/m². Those of skill in the art readily recognize that the invention method is not limited to those who fall within the above criteria. Indeed, the method of the invention can also be advantageously practiced by individuals who fall outside of these traditional criteria, for example, by those who may be prone to obesity.

The term “inflammatory disorders”, as used herein, refers to disorders such as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, psoriasis, chondrocalcinosis, gout, inflammatory bowel disease, ulcerative colitis, Crohn's disease, fibromyalgia, and cachexia.

The phrase “therapeutically effective amount”, as used herein, refers to the amount of drug or pharmaceutical agent that will elicit the biological or medical response of a tissue, system, animal, or human that is being sought by a researcher, veterinarian, medical doctor or other.

The phrase “amount . . . effective to lower blood glucose levels”, as used herein, refers to levels of compound sufficient to provide circulating concentrations high enough to accomplish the desired effect. Such a concentration typically falls in the range of about 10 nM up to 2 μM; with concentrations in the range of about 100 nM up to 500 nM being preferred. As noted previously, since the activity of different compounds which fall within the definition of formula I as set forth above may vary considerably, and since individual subjects may present a wide variation in severity of symptoms, it is up to the practitioner to determine a subject's response to treatment and vary the dosages accordingly.

The phrase “insulin resistance”, as used herein, refers to the reduced sensitivity to the actions of insulin in the whole body or individual tissues, such as skeletal muscle tissue, myocardial tissue, fat tissue or liver tissue. Insulin resistance occurs in many individuals with or without diabetes mellitus.

The phrase “insulin resistance syndrome”, as used herein, refers to the cluster of manifestations that include insulin resistance, hyperinsulinemia, non-insulin dependent diabetes mellits (NIDDM), arterial hypertension, central (visceral) obesity, and dyslipidemia.

The compounds of the present invention may also be useful in the treatment of other metabolic disorders associated with impaired glucose utilization and insulin resistance including major late-stage complications of NIDDM, such as diabetic angiopathy, atherosclerosis, non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease, diabetic nephropathy, diabetic neuropathy, and diabetic ocular complications such as retinopathy, cataract formation and glaucoma, and many other complications linked to NIDDM, including dyslipidemia, glucocorticoid-induced insulin resistance, polycystic ovarian syndrome, obesity, hyperglycemia, hyperlipidemia, hypercholesteremia, hypertriglyceridemia, hyperinsulinemia, and hypertension. Brief descriptions of these conditions are available in any medical dictionary, for instance, “Stedman's Medical Dictionary” (Xth Ed.).

Compounds and compositions disclosed herein can be administered in therapeutically effective amounts in combination with one or more additional therapeutic agents as defined herein. For example, synergistic effects can occur with other substances used in the treatment of Cry-mediated diseases or disorders. Where the compounds of the invention are administered in conjunction with other therapies, dosages of the co-administered compounds will of course vary depending on the type of co-drug employed, on the specific drug employed, on the condition being treated and so forth.

As used herein, the terms “combination treatment”, “combination therapy”, “combined treatment” or “combinatorial treatment”, used interchangeably, refer to a treatment of an individual with at least two different therapeutic agents. The terms “co-administration” or “combined administration” or the like as utilized herein are meant to encompass administration of the selected therapeutic agents to a single subject, and are intended to include treatment regimens in which the agents are not necessarily administered by the same route of administration or at the same time. The term “pharmaceutical combination” means a product that results from the mixing or combining of more than one active ingredient and includes both fixed and non-fixed combinations of the active ingredients. A “fixed combination” means that the active ingredients, e.g. a compound as disclosed herein and an additional therapeutic agent, are both administered to a patient simultaneously in the form of a single entity or dosage. A “non-fixed combination” means that the active ingredients, e.g. a compound as disclosed herein and an additional therapeutic agent, are both administered to a patient as separate entities either simultaneously, concurrently or sequentially with no specific time limits, wherein such administration provides therapeutically effective levels of the 2 compounds in the body of the patient. The latter also applies to cocktail therapy, e.g. the administration of 3 or more active ingredients.

Another embodiment of the present invention is a method of identifying patients in need of treatment based on measuring clock gene (e.g. Cry1 and Cry2) expression levels in samples taken from a subject (Bjarnason, G. A. et al. Am. J. Pathol. 2001, 158, 1793; Akashi, M. et. al. Proc. Natl. Acad. Sci. USA, 2010, 107, 15643). Rhythmic mRNA expression profiles for human clock genes, including Cry1 and Cry2, measured in samples from a subject indicate a circadian clock is present in peripheral tissues (Mohawk, J. A. et al. Ann. Rev. Neurosci. 2012, Epub ahead of print). Expression of circadian clock related genes in these samples has been demonstrated to vary during the day. Furthermore, clock gene (e.g. Cry1 and Cry2) expression patterns in peripheral blood mononuclear cells are altered in humans by diseases such as obesity (Tahira, K. et al. Arch. Med. Sci. 2011, 7, 933). Changes in clock gene (e.g. Cry1 and Cry2) expression in peripheral mononuclear blood cells can be correlated with serum leptin, adiponectin, insulin and hsCRP levels, plasma lipid, glucose, melatonin and cortisol levels and, in animals, expression of clock genes (e.g. Cry1 and Cry2) in tissues including liver, adipose, pancreas and skeletal muscle. By contacting samples taken from a subject treated with a compound of formula I and measuring rhythmic mRNA or protein expression profiles, patients in need of treatment may be identified and pharmacological activity can be assessed. In other embodiments, the activities of one or more cryptochromes may be assessed, for example, the ability of cryptochromes to bind to a target such as Per1, Per2, glucocorticoid receptor (GR), or a promoter sequence containing Cry recognition sites, such as, e.g., the CLOCK-BMAL1 promoter.

Accordingly, one aspect of the subject matter disclosed herein relates to a method of monitoring progression or prognosis of a Cry-mediated disease or disorder in a subject, comprising measuring an effective amount of one or more cryptochromes in a first sample from the subject at a first period of time; measuring an affective amount of one or more cryptochromes in a second sample from the subject at a second period of time; and comparing the amount of the one or more cryptochromes detected in the first sample to the amount of the one or more cryptochromes detected in the second sample, or to a reference value.

“Diagnosis”, “diagnose”, “prognose” or “prognosis” is not limited to a definitive or near definitive determination that an individual has a disease, but also includes determining that an individual has an increased likelihood of having or developing the disease, compared to healthy individuals or to the general population.

As used herein, “expression” and “expression levels” include but are not limited to one or more of the following: transcription of the gene into precursor mRNA; splicing and other processing of the precursor mRNA to produce mature mRNA; mRNA stability; translation of the mature mRNA into protein (including codon usage and tRNA availability); and glycosylation and/or other modifications of the translation product, if required for proper expression and function.

A “formula,” “algorithm,” or “model” is any mathematical equation, algorithmic, analytical or programmed process, or statistical technique that takes one or more continuous or categorical inputs (herein called “parameters”) and calculates an output value, sometimes referred to as an “index” or “index value.” Non-limiting examples of “algorithms” include sums, ratios, and regression operators, such as coefficients or exponents, value transformations and normalizations (including, without limitation, those normalization schemes based on clinical parameters, such as gender, age, body mass index, or ethnicity), rules and guidelines, statistical classification models, and neural networks trained on historical populations. Of particular use in measuring Cry as defined herein are linear and non-linear equations and statistical classification analyses to “correlate” the relationship between levels of Cry detected in a subject sample and the subject's risk of developing a Cry-mediated disease or disorder.

“Measuring” or “measurement” means assessing the presence, absence, quantity or amount (which can be an effective amount) of either a given substance within a clinical or subject-derived sample, including the derivation of qualitative or quantitative concentration levels of such substances, or otherwise evaluating the values or categorization of a subject's clinical parameters. Measurement or measuring may also involve qualifying the type or identifying the substance. Measurement or measuring may also involve the ability of one or more Cry to bind to a target, wherein the target may be period genes or proteins Per1 and Per2, glucocorticoid receptor (GR), or the promoter region of the CLOCK-BMAL1 gene. Measurement of Cry may be used to diagnose, detect, or identify a Cry-mediated disease or disorder in a subject, to monitor the progression or prognosis of a Cry-mediated disease or disorder in a subject, to predict the recurrence of a Cry-mediated disease or disorder in a subject, or to classify a subject as having a low risk or a high risk of developing a Cry-mediated disease or disorder or a recurrence of a Cry-mediated disease or disorder.

“Risk” in the context of the present invention relates to the probability that an event will occur over a specific time period, as in the development of Cry-mediated disease or disorder, and can mean a subject's “absolute” risk or “relative” risk. Absolute risk can be measured with reference to either actual observation post-measurement for the relevant time cohort, or with reference to index values developed from statistically valid historical cohorts that have been followed for the relevant time period. Relative risk refers to the ratio of absolute risks of a subject compared either to the absolute risks of low risk cohorts or an average population risk, which can vary by how clinical risk factors are assessed. Odds ratios, the proportion of positive events to negative events for a given test result, are also commonly used (odds are according to the formula p/(1−p) where p is the probability of event and (1−p) is the probability of no event) to no-conversion. Alternative continuous measures which may be assessed in the context of the present invention include time to development of a Cry-mediated disease or disorder, or progression to a different stage of a Cry-mediated disease or disorder, including progression or development of a Cry-mediated disease or disorder and therapeutic conversion risk reduction ratios.

“Risk evaluation,” or “evaluation of risk” in the context of the subject matter disclosed herein encompasses making a prediction of the probability, odds, or likelihood that an event or disease state may occur, the rate of occurrence of the event or conversion from one disease state to another, i.e., from a “normal” condition to an at-risk condition for developing a Cry-mediated disease or disorder, or from an at-risk condition to a Cry-mediated disease or disorder, or development of recurrent disease or disorder. Risk evaluation can also comprise prediction of other indices of Cry-mediated disease or disorder, either in absolute or relative terms in reference to a previously measured population. The methods of the present invention may be used to make continuous or categorical measurements of the risk of conversion to a Cry-mediated disease or disorder, thus diagnosing and defining the risk spectrum of a category of subjects defined as at risk for developing the disease or disorder. In the categorical scenario, the invention can be used to discriminate between normal and at-risk subject cohorts. In other embodiments, the present invention may be used so as to discriminate at-risk conditions from disease conditions, or disease conditions from normal.

A “sample” as used herein is a biological sample isolated from a subject and can include, by way of example and not limitation, whole blood, serum, plasma, blood cells, endothelial cells, tissue biopsies, lymphatic fluid, ascites fluid, interstitial fluid (also known as “extracellular fluid” and encompasses the fluid found in spaces between cells, including, inter alia, gingival crevicular fluid), bone marrow, seminal fluid, cerebrospinal fluid (CSF), saliva, mucous, sputum, sweat, urine, or any other secretion, excretion, or other bodily fluids.

By “statistically significant”, it is meant that the alteration is greater than what might be expected to happen by chance alone (which could be a “false positive”). Statistical significance can be determined by any method known in the art. Commonly used measures of significance include the p-value, which presents the probability of obtaining a result at least as extreme as a given data point, assuming the data point was the result of chance alone. A result is often considered highly significant at a p-value of 0.05 or less.

The risk of a Cry-mediated disease or disorder can be detected by measuring an “effective amount” of one or more cryptochromes in a sample (e.g., a subject derived sample), and comparing the effective amounts to reference values, often utilizing mathematical algorithms or formulae in order to combine information from results of multiple individuals into a single measurement. Subjects identified as having an increased risk of a Cry-mediated disease or disorder can optionally be selected to receive treatment regimens or therapeutic interventions, such as administration of the compounds of formula I as defined herein as monotherapy or in combination with one or more additional therapeutic agents, or implementation of surgical interventions (which may follow or precede administration of the compounds of formula I, alone or in combination with additional therapeutic agents or other therapies).

The methods for detecting these cryptochromes in a sample have many applications. For example, one or more cryptochromes can be measured to aid diagnosis or prognosis of a Cry-mediated disease or disorder. In another example, the methods for detection of the cryptochromes can be used to monitor responses in a subject to treatment of a Cry-mediated disease or disorder. In another example, the methods can be used to assay for and to identify compounds that modulate expression of cryptochromes in vivo or in vitro.

The present invention may be used to make continuous or categorical measurements of the risk of conversion to a Cry-mediated disease or disorder, thus diagnosing and defining the risk spectrum of a category of subjects defined as being at-risk for developing the disease or disorder. In the categorical scenario, the methods of the present invention can be used to discriminate between normal and at-risk subject cohorts. In other embodiments, the present invention may be used so as to discriminate at-risk from disease, or disease from normal. Such differing use may require different combinations in individual panel or profile, mathematical algorithm, and/or cut-off points, but be subject to the same aforementioned measurements of accuracy for the intended use.

Identifying the at-risk subject enables the selection and initiation of various therapeutic interventions or treatment regimens in order to delay, reduce, or prevent that subject's conversion to a Cry-mediated disease or disorder. Levels of an effective amount of cryptochrome proteins, nucleic acids, polymorphisms, metabolites, or other analytes also allows for the course of treatment to be monitored. In this method, a biological sample can be provided from a subject undergoing treatment regimens, e.g., therapeutic treatments, for a Cry-mediated disease or disorder. Such treatment regimens can include, but are not limited to, surgical intervention and treatment with therapeutic agents used in subjects diagnosed or identified with a Cry-mediated disease or disorder, for example, the compounds of formula I described herein. If desired, biological samples are obtained from the subject at various time points before, during, or after treatment. For example, determining the disease status by comparison of a subject's cryptochrome profile to a reference cryptochrome profile can be repeated more than once, wherein the subject's profile can be obtained from a separate sample taken each time the method is repeated. Samples may be taken from the subject at defined time intervals, such as, e.g., 4 hours, 8 hours, 12 hours, 24 hours, 48 hours, 72 hours, or any suitable time interval as would be performed by those skilled in the art.

Differences in the genetic makeup of subjects can result in differences in their relative abilities to metabolize various drugs, which may modulate the symptoms or risk factors of a Cry-mediated disease or disorder. Subjects that have a Cry-mediated disease or disorder, or are at risk for developing a Cry-mediated disease or disorder can vary in age, ethnicity, and other parameters. Accordingly, measuring effective amounts of one or more cryptochromes as defined herein, both alone and together in combination with known genetic factors for drug metabolism, allow for a pre-determined level of predictability that a putative therapeutic or prophylactic to be tested in a selected subject will be suitable for treating or preventing a Cry-mediated disease or disorder in the subject.

To identify therapeutic agents or drugs that are appropriate for a specific subject, a test sample from the subject can also be exposed to a therapeutic agent or a drug, and the level or activity of one or more of cryptochrome proteins, nucleic acids, polymorphisms, splice variants, metabolites or other analytes can be determined. Other genes or proteins that are affected or which directly or indirectly bind to one or more cryptochromes (e.g., Per1, Per2, GR, CLOCK-BMAL1 promoter, etc.) may also be measured. The level of one or more cryptochromes can be compared to sample derived from the subject before and after subject management for a Cry-mediated disease or disorder, e.g., treatment or exposure to a therapeutic agent or a drug, or can be compared to samples derived from one or more subjects who have shown improvements in risk factors as a result of such treatment or exposure.

Nucleic acids may be obtained from the samples in many ways known to one of skill in the art, for example, extraction methods, including e.g., solvent extraction, affinity purification and centrifugation. Selective precipitation can also purify nucleic acids. Chromatography methods may also be utilized including, gel filtration, ion exchange, selective adsorption, or affinity binding. The nucleic acids may be, for example, RNA, DNA or may be synthesized into cDNA. The nucleic acids may be detected using microarray techniques that are well known in the art, for example, Affymetrix arrays followed by multidimensional scaling techniques. See R. Ekins, R. and Chu, F. W. (1999) Trends Biotechnol. 17: 217-218; D. D. Shoemaker, et al., (2001) Nature 409(6822): 922-927 and U.S. Pat. No. 5,750,015.

If desired, the sample can be prepared to enhance detectability of one or more cryptochromes by, for example, pre-fractionation. Methods of pre-fractionation include, for example, Cibacron blue agarose chromatography, size exclusion chromatography, ion exchange chromatography, heparin chromatography, lectin chromatography, affinity chromatography, single stranded DNA affinity chromatography, sequential extraction, gel electrophoresis and liquid chromatography. The analytes also may be modified prior to detection. A sample can be pre-fractionated by removing proteins that are present in a high quantity or that may interfere with the detection of molecules of interest in a sample. For example, in a blood serum sample, serum albumin is present in a high quantity and may obscure the analysis of one or more cryptochromes. Thus, a blood serum sample can be pre-fractionated by removing serum albumin using, for example, a substrate that comprises adsorbents that specifically bind serum albumin, an affinity column or anti-serum albumin antibodies can be used.

In other embodiments, molecules of interest in a sample can be separated by high-resolution electrophoresis, e.g., one or two-dimensional gel electrophoresis. A fraction can be isolated and further analyzed by gas phase ion spectrometry. Preferably, two-dimensional gel electrophoresis is used to generate two-dimensional array of spots, including one or more cryptochromes. See, e.g., Jungblut and Thiede, (1997) Mass Spectr. Rev. 16: 145-162. The two-dimensional gel electrophoresis can be performed using methods known in the art. See, e.g., Deutscher ed., Methods in Enzymology vol. 182. Typically, a sample may be separated by, e.g., isoelectric focusing, during which one or more cryptochromes in a sample are separated in a pH gradient until they reach a spot where their net charge is zero (i.e., isoelectric point). This first separation step results in one-dimensional array. The molecules in one-dimensional array are further separated using a technique generally distinct from that used in the first separation step. For example, in the second dimension, molecules of interest separated by isoelectric focusing are further separated using a polyacrylamide gel, such as polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate (SDS-PAGE). SDS-PAGE gel allows further separation based on molecular mass. Typically, two-dimensional gel electrophoresis can separate chemically different molecules of interest in the molecular mass range from 1000-200,000 Da within complex mixtures.

Molecules of interest in the two-dimensional array can be detected using any suitable methods known in the art. For example, molecules of interest in a gel can be labeled or stained (e.g., Coomassie Blue or silver staining). If gel electrophoresis generates spots that correspond to the molecular weight of one or more cryptochromes of the invention, the spot can be excised and further analyzed by, for example, gas phase ion spectrometry, mass spectrometry, or high performance liquid chromatography. Alternatively, the gel containing molecules of interest can be transferred to an inert membrane by applying an electric field. Then a spot on the membrane that approximately corresponds to the molecular weight of a molecule of interest can be analyzed by e.g., gas phase ion spectrometry, mass spectrometry, or HPLC.

Optionally, a molecule of interest can be modified before analysis to improve its resolution or to determine its identity. For example, the sample may be subject to proteolytic digestion before analysis. Any protease can be used. Proteases, such as trypsin, that are likely to cleave proteins into a discrete number of fragments are particularly useful. The fragments that result from digestion may function as a fingerprint for the molecules of interest, thereby enabling their indirect detection. This is particularly useful where there are molecules of interest with similar molecular masses that might be confused for the preferred molecule, i.e., cryptochromes, in question. Also, proteolytic fragmentation is useful for high molecular weight molecules because smaller molecules are more easily resolved by mass spectrometry. In another example, molecules can be modified to improve detection resolution. For instance, neuraminidase can be used to remove terminal sialic acid residues from glycoproteins to improve binding to an anionic adsorbent (e.g., cationic exchange arrays) and to improve detection resolution. In another example, the molecules can be modified by the attachment of a tag of particular molecular weight that specifically binds to another molecular entity, further distinguishing them. Optionally, after detecting such modified molecules of interest, the identity of the molecules can be further determined by matching the physical and chemical characteristics of the modified versions in a protein database (e.g., SwissProt).

Once captured on a substrate, e.g., biochip or antibody, any suitable method, such as those described herein as well as other methods known in the art, can be used to measure one or more cryptochromes in a sample. The actual measurement of levels or amounts of the such molecules can be determined using any method known in the art. These methods include, without limitation, mass spectrometry (e.g., laser desorption/ionization mass spectrometry), fluorescence (e.g. sandwich immunoassay), surface plasmon resonance, ellipsometry and atomic force microscopy. Methods may further include, by one or more of microarrays, PCR methods, mass spectrometry (including, for example, and without limitation, ESI-MS, ESI-MS/MS, ESI-MS/(MS)n, matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS), surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS), desorption/ionization on silicon (DIOS), secondary ion mass spectrometry (SIMS), quadrupole time-of-flight (Q-TOF), atmospheric pressure chemical ionization mass spectrometry (APCI-MS), APCI-MS/MS, APCI-(MS)n, atmospheric pressure photoionization mass spectrometry (APPI-MS), APPI-MS/MS, and APPI-(MS)n, quadrupole mass spectrometry, Fourier transform mass spectrometry (FTMS), and ion trap mass spectrometry), nucleic acid chips, Northern blot hybridization, TMA, SDA, NASBA, PCR, real time PCR, reverse transcriptase PCR, real time reverse transcriptase PCR, in situ PCR, chromatographic separation coupled with mass spectrometry, protein capture using immobilized antibodies or by traditional immunoassays. See for example, U.S. Pat. Nos. 5,723,591; 5,801,155 and 6,084,102 and Higuchi, 1992 and 1993. PCR assays may be done, for example, in a multi-well plate formats or in chips, such as the BioTrove OPEN ARRAY Chips (BioTrove, Woburn, Mass.).

For example, sequences within the sequence database entries corresponding to cryptochromes can be used to construct probes for detecting RNA sequences in, e.g., Northern blot hybridization analyses or methods which specifically, and, preferably, quantitatively amplify specific nucleic acid sequences. As another example, the sequences can be used to construct primers which specifically or selectively hybridize to cryptochrome sequences and which are used to amplifying such sequences in, e.g., amplification-based detection methods such as reverse-transcription based polymerase chain reaction (RT-PCR), e.g., quantitative real-time RT-PCR. When alterations in gene expression are associated with gene amplification, deletion, polymorphisms, and mutations, sequence comparisons in test and reference populations can be made by comparing relative amounts of the examined DNA sequences in subject and reference cell populations. As used herein, the term “specifically (or selectively) hybridizes” when referring to a nucleic acid, refers to a binding reaction that is determinative of the presence of the nucleic acid in a heterogeneous population of nucleic acids. Thus, under designated assay conditions, the specified nucleic acid probe (including inhibitory nucleic acids) may bind or hybridize to a particular nucleic acid of interest at least two times the background and do not substantially bind or hybridize in a significant amount to other nucleic acids present in the sample.

Levels of cryptochromes can also be determined by immunoassay. The antibody may be monoclonal, polyclonal, chimeric, or a fragment of the foregoing, as discussed in detail herein, and the step of detecting the reaction product may be carried out with any suitable immunoassay. The phrase “specifically (or selectively) binds” to an antibody or “specifically (or selectively) immunoreactive with,” when referring to a protein or peptide, refers to a binding reaction that is determinative of the presence of the protein in a heterogeneous population of proteins and other biologies. Thus, under designated immunoassay conditions, the specified antibodies bind to a particular protein at least two times the background and do not substantially bind in a significant amount to other proteins present in the sample. Specific binding to an antibody under such conditions may require an antibody that is selected for its specificity for a particular protein. For example, polyclonal antibodies raised to a cryptochrome from specific species such as rat, mouse, or human can be selected to obtain only those polyclonal antibodies that are specifically immunoreactive with that cryptochrome and not with other proteins, except for polymorphic variants and alleles of the cryptochrome. This selection may be achieved by subtracting out antibodies that cross-react with cryptochromes from other species.

Immunoassays carried out in accordance with the present invention may be homogeneous assays or heterogeneous assays. In a homogeneous assay the immunological reaction usually involves the specific antibody (e.g., anti-cryptochrome protein antibody), a labeled analyte, and the sample of interest. The signal arising from the label is modified, directly or indirectly, upon the binding of the antibody to the labeled analyte. Both the immunological reaction and detection of the extent thereof can be carried out in a homogeneous solution. Immunochemical labels which may be employed include free radicals, radioisotopes, fluorescent dyes, enzymes, bacteriophages, or coenzymes.

In a heterogeneous assay approach, the reagents are usually the sample, the antibody, and means for producing a detectable signal. Samples as described above may be used. The antibody can be immobilized on a support, such as a bead (such as protein A and protein G agarose beads), plate or slide, and contacted with the specimen suspected of containing the antigen in a liquid phase. The support is then separated from the liquid phase and either the support phase or the liquid phase is examined for a detectable signal employing means for producing such signal. The signal is related to the presence of the analyte in the sample. Means for producing a detectable signal include the use of detectable labels. Exemplary detectable labels include magnetic beads (e.g., DYNABEADS™), fluorescent dyes, enzymes (e.g., horse radish peroxide, alkaline phosphatase and others commonly used in an ELISA), radiolabels (e.g., ³⁵S, ¹²⁵I, ¹³¹I), and fluorescent labels (e.g., fluorescein, Alexa, green fluorescent protein, rhodamine) and colorimetric labels such as colloidal gold or colored glass or plastic beads in accordance with known techniques.

Alternatively, the molecule of interest in the sample can be detected using an indirect assay, wherein, for example, a second, labeled antibody is used to detect bound cryptochrome-specific antibody, and/or in a competition or inhibition assay wherein, for example, a monoclonal antibody which binds to a distinct epitope of the cryptochrome is incubated simultaneously with the mixture. For example, if the antigen to be detected contains a second binding site, an antibody which binds to that site can be conjugated to a detectable group and added to the liquid phase reaction solution before the separation step. The presence of the detectable label on the solid support indicates the presence of the antigen in the test sample. Methods for measuring the amount or the presence of antibody-antigen complexes include, for example, detection of fluorescence, luminescence, chemiluminescence, absorbance, reflectance, transmittance, birefringence or refractive index (e.g., surface plasmon resonance, ellipsometry, a resonant mirror method, a grating coupler waveguide method or interferometry). Optical methods include microscopy (both confocal and non-confocal), imaging methods and non-imaging methods. Electrochemical methods include voltametry and amperometry methods. Radio frequency methods include multipolar resonance spectroscopy. Examples of suitable immunoassays include, but are not limited to immunoblotting (e.g., Western blotting, slot blot assay), immunoprecipitation, immunofluorescence methods, chemiluminescence methods, electrochemiluminescence (ECL) or enzyme-linked immunoassays, e.g., enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA). See generally E. Maggio, Enzyme-Immunoassay, (1980) (CRC Press, Inc., Boca Raton, Fla.); see also U.S. Pat. Nos. 4,727,022; 4,659,678; 4,376,110; 4,275,149; 4,233,402; and 4,230,767. These methods are also described in, e.g., Methods in Cell Biology: Antibodies in Cell Biology, volume 37 (Asai, ed. 1993); Basic and Clinical Immunology (Stites & Terr, eds., 7th ed. 1991); and Harlow & Lane, supra. All of these are incorporated by reference herein.

Immunoassays can be used to determine presence or absence of one or more cryptochromes in a sample as well as the quantity in a sample. The amount of an antibody-marker complex can be determined by comparing to a standard. A standard can be, e.g., a known compound or another protein known to be present in a sample. As noted above, the test amount of the one or more cryptochromes need not be measured in absolute units, as long as the unit of measurement can be compared to a control.

Proteins frequently exist in a sample in a plurality of different forms characterized by a detectably different mass. These forms can result from either, or both, of pre- and post-translational modification. Pre-translational modified forms include allelic variants, slice variants and RNA editing forms. Post-translationally modified forms include forms resulting from proteolytic cleavage (e.g., fragments of a parent protein), glycosylation, phosphorylation, lipidation, oxidation, methylation, cystinylation, sulphonation and acetylation. Antibodies can also be useful for detecting post-translational modifications of proteins, polypeptides, mutations, and polymorphisms, such as tyrosine phosphorylation, threonine phosphorylation, serine phosphorylation, glycosylation (e.g., O-GlcNAc). Such antibodies specifically detect the phosphorylated amino acids in a protein or proteins of interest, and can be used in immunoblotting, immunofluorescence, and ELISA assays described herein. These antibodies are well-known to those skilled in the art, and commercially available. Post-translational modifications can also be determined using metastable ions in reflector matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF) (Wirth, U. et al. (2002) Proteomics 2(10): 1445-51). The collection of proteins including a specific protein and all modified forms of it is referred to herein as a “protein cluster.” The collection of all modified forms of a specific protein, excluding the specific protein, itself, is referred to herein as a “modified protein cluster.” Modified forms of any cryptochrome also may be used, themselves, in the methods disclosed herein. In certain cases the modified forms may exhibit better discriminatory power in diagnosis than the specific forms set forth herein. Modified forms can be initially detected by any methodology known in the art.

Alternatively, cryptochrome protein and nucleic acid metabolites can be measured. The term “metabolite” includes any chemical or biochemical product of a metabolic process, such as any compound produced by the processing, cleavage or consumption of a biological molecule (e.g., a protein, nucleic acid, carbohydrate, or lipid). Metabolites can be detected in a variety of ways known to one of skill in the art, including the refractive index spectroscopy (RI), ultra-violet spectroscopy (UV), fluorescence analysis, radiochemical analysis, near-infrared spectroscopy (near-IR), nuclear magnetic resonance spectroscopy (NMR), light scattering analysis (LS), mass spectrometry, pyrolysis mass spectrometry, nephelometry, dispersive Raman spectroscopy, gas chromatography combined with mass spectrometry, liquid chromatography (including high-performance liquid chromatography (HPLC)), which may be combined with mass spectrometry, matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) combined with mass spectrometry, ion spray spectroscopy combined with mass spectrometry, capillary electrophoresis, ion mobility spectrometry, surface-enhanced laser desorption/ionization (SELDI), optical methods, electrochemical methods, atomic force microscopy, radiofrequency methods, surface Plasmon resonance, ellipsometry, NMR and IR detection. (See, International Application Publication Nos. WO 04/056456 and WO 04/088309, each of which are hereby incorporated by reference in their entireties). In this regard, other analytes can be measured using the above-mentioned detection methods, or other methods known to the skilled artisan. For example, circulating calcium ions (Ca2+) can be detected in a sample using fluorescent dyes such as the Fluo series, Fura-2A, Rhod-2, among others. Other metabolites can be similarly detected using reagents that specifically designed or tailored to detect such metabolites.

A Cry-mediated disease or disorder may involve changes in the activity of one or more cryptochromes, or ability of one or more cryptochromes to bind to a target. Without wishing to be bound by theory, cryptochrome proteins are believed to bind to Period proteins Per 1 and/or Per2 as a heterodimer, which then bind to the promoter region of the CLOCK-BMAL1 gene to facilitate transcriptional repression in a feedback loop that can impinge upon numerous metabolic processes. Thus, measuring an effective amount of one or more cryptochromes according to the methods of the invention may involve assessing an increase or decrease in the ability of Cry proteins to bind to Per1 and/or Per2, to the glucocorticoid receptor (GR), or any other binding target of Cry known to those skilled in the art. Measurement of protein-protein interactions may be facilitated by any method known in the art, including co-immunoprecipitation, yeast two-hybrid assay, surface Plasmon resonance, bimolecular fluorescence complementation, tandem affinity purification, phage display, fluorescence polarization/anisotropy, dual polarization interferometry, fluorescence correlation spectroscopy, fluorescence resonance energy transfer, and the like.

The activity of one or more cryptochromes may also be measured by an increase or decrease in the ability to bind to a DNA sequence, i.e., the promoter region of the CLOCK-BMAL1 gene, or other gene that contains binding sites recognized by one or more cryptochromes. “Promoter”, “promoter sequence”, or “promoter region” refers to a DNA sequence capable of binding RNA polymerase in a cell, initiating transcription of a downstream (3′ direction) coding sequence, thereby controlling its expression. For purposes of defining the present invention, the promoter sequence is bounded at its 3′ terminus by the transcription initiation site and extends upstream (5′ direction) to include the minimum number of bases or elements necessary to initiate transcription at levels detectable above background. Within the promoter sequence will be found a transcription initiation site (conveniently defined for example, by mapping with nuclease S1), as well as protein binding domains (consensus sequences) responsible for the binding of RNA polymerase. Promoters may be derived in their entirety from a native gene, or be composed of different elements derived from different promoters found in nature, or even comprise synthetic DNA segments. In most cases the exact boundaries of regulatory sequences have not been completely defined, DNA fragments of different lengths may have identical promoter activity.

The CLOCK-BMAL1 promoter (or any other promoter region containing binding or recognition sites for Cry) may be “operably linked” to a reporter gene. The term “operably linked” refers to the association of nucleic acid sequences on a single nucleic acid fragment so that the function of one is affected by the other. For example, a promoter is operably linked with a coding sequence when it is capable of affecting the expression of that coding sequence (i.e., that the coding sequence is under the transcriptional control of the promoter). Coding sequences can be operably linked to regulatory sequences in sense or antisense orientation. The term “reporter gene” means a nucleic acid encoding an identifying factor that is able to be identified based upon the reporter gene's effect, wherein the effect is used to track the inheritance of a nucleic acid of interest, to identify a cell or organism that has inherited the nucleic acid of interest, and/or to measure gene expression induction or transcription. Examples of reporter genes known and used in the art include: luciferase (Luc), green fluorescent protein (GFP), alkaline phosphatase (ALP), chloramphenicol acetyltransferase (CAT), β-galactosidase (LacZ), β-glucuronidase (Gus), and the like. Selectable marker genes may also be considered reporter genes. The promoter-reporter gene construct may be contained in a plasmid or expression vector that is transferred or transfected into a cell. The expression of the reporter gene can be detected by determining the activity of the gene product, for example, an enzyme activity in the case of using a reporter gene exemplified above.

The term “plasmid” refers to an extra chromosomal element often carrying a gene that is not part of the central metabolism of the cell, and usually in the form of circular double-stranded DNA molecules. Such elements may be autonomously replicating sequences, genome integrating sequences, phage or nucleotide sequences, linear, circular, or supercoiled, of a single- or double-stranded DNA or RNA, derived from any source, in which a number of nucleotide sequences have been joined or recombined into a unique construction which is capable of introducing a promoter fragment and DNA sequence for a selected gene product along with appropriate 3′ untranslated sequence into a cell. The term “expression vector” means a vector, plasmid or vehicle designed to enable the expression of an inserted nucleic acid sequence following transformation into the host. Vectors may be introduced into the desired host cells by methods known in the art, e.g., transfection, electroporation, microinjection, transduction, cell fusion, DEAE dextran, calcium phosphate precipitation, lipofection (lysosome fusion), use of a gene gun, or a DNA vector transporter. Any cell may be used to carry out reporter assays, such as a prokaryotic cell or eukaryotic cell. Preferably, the cell may be a bacterial cell, a fungal cell, a yeast cell, a nematode cell, an insect cell, a fish cell, a plant cell, an avian cell, an animal cell, and a mammalian cell. Cells may be primary cells or may be continuously passaged as cell lines. Exemplary cells and cell lines are known to those skilled in the art.

Other methods of measuring the activity or ability of one or more cryptochromes to bind to a DNA sequence include chromatin immunoprecipitation assay, electrophoretic mobility shift assay, DNA pull-down assay, microplate capture and detection, and the like.

Levels of an effective amount of cryptochrome proteins, nucleic acids, polymorphisms, metabolites, or other analytes, or the activities of cryptochrome proteins or targets that are directly or indirectly bound to cryptochrome proteins, can then be determined and compared to a reference value, e.g. a control subject or population whose disease status is known, or an index value or baseline value. The reference sample or index value or baseline value may be taken or derived from one or more subjects who have been exposed to the treatment, or may be taken or derived from one or more subjects who are at low risk of developing a Cry-mediated disease or disorder, or may be taken or derived from subjects who have shown improvements in disease risk factors as a result of exposure to treatment. Alternatively, the reference sample or index value or baseline value may be taken or derived from one or more subjects who have not been exposed to the treatment. For example, samples may be collected from subjects who have received initial treatment for a Cry-mediated disease or disorder and subsequent treatment for the disease or disorder to monitor the progress of the treatment. In some embodiments, a first sample may be taken from a subject at a first period of time, e.g., prior to treatment with a compound of formula I as defined herein, either alone or in combination with one or more additional therapeutic agents, followed by measuring or detecting one or more cryptochromes (or cryptochrome targets) as described herein. Thereafter, a second sample may be taken from a subject at a second period of time, e.g., after treatment with a compound of formula I as defined herein, either alone or in combination with one or more additional therapeutic agents, and measuring the one or more cryptochromes or cryptochrome targets. Any number of samples may be taken at any time interval throughout the course of treatment to assess its effectiveness.

A reference value can also comprise a value derived from risk prediction algorithms or computed indices from population studies such as those disclosed herein. A similar term in this context is a “control”, which can be, e.g., the average or median amount of cryptochromes present in comparable samples of normal subjects in normal subjects or in non-disease subjects such as where a Cry-mediated disease or disorder is undetectable. The control amount is measured under the same or substantially similar experimental conditions as in measuring the test amount. The correlation may take into account the presence or absence of the cryptochromes in a test sample and the frequency of detection of the same molecules in a control. The correlation may take into account both of such factors to facilitate determination of disease status.

A reference profile of those subjects who do not have a Cry-mediated disease or disorder, and would not be expected to develop a Cry-mediated disease or disorder may also be prepared according to methods disclosed herein. Measurement of one or more cryptochromes can also be used to generate a “subject profile” taken from subjects who have a Cry-mediated disease or disorder. The subject profiles can be compared to a reference profile to diagnose or identify subjects at risk for developing a Cry-mediated disease or disorder, to monitor the progression of disease, as well as the rate of progression of disease, and to monitor the effectiveness of treatment modalities or subject management.

The reference and subject profiles of the present invention can be contained in a machine-readable medium, such as but not limited to, analog or digital tapes like those readable by a VCR, CD-ROM, DVD-ROM, USB flash media, among others. Such machine-readable media can also contain additional test results, such as, without limitation, measurements of clinical parameters and traditional laboratory risk factors. Alternatively or additionally, the machine-readable media can also comprise subject information such as medical history and any relevant family history. The machine-readable media can also contain information relating to other risk algorithms and computed indices such as those described herein.

In any of the methods disclosed herein, the data from the sample may be fed directly from the detection means into a computer containing the diagnostic algorithm. Alternatively, the data obtained can be fed manually, or via an automated means, into a separate computer that contains the diagnostic algorithm. Accordingly, embodiments of the invention include methods involving correlating the detection of the cryptochromes with a probable diagnosis of a Cry-mediated disease or disorder. The correlation may take into account the amount of the one or more cryptochromes in the sample compared to a control amount (up or down regulation of the cryptochromes) (e.g., in normal subjects in whom a Cry-mediated disease or disorder is undetectable). The correlation may take into account the presence or absence of the cryptochromes in a test sample and the frequency of detection of the same molecules in a control. The correlation may take into account both of such factors to facilitate determination of whether a subject has a Cry-mediated disease or disorder or not.

Data analysis can include the steps of determining signal strength (e.g., height of peaks) of a marker detected and removing “outliers” (data deviating from a predetermined statistical distribution). The observed peaks can be normalized, a process whereby the height of each peak relative to some reference is calculated. For example, a reference can be background noise generated by instrument and chemicals (e.g., energy absorbing molecule) which is set as zero in the scale. The signal strength detected for each molecule of interest can be displayed in the form of relative intensities in the scale desired (e.g., 100). Alternatively, a standard (e.g., a serum protein) may be admitted with the sample so that a peak from the standard can be used as a reference to calculate relative intensities of the signals observed for each molecule of interest detected.

The resulting data can be transformed or converted into various formats for displaying. In one format, referred to as “spectrum view or retentate map,” a standard spectral view can be displayed, wherein the view depicts the quantity of molecule reaching the detector at each particular molecular weight. In another format, referred to as “peak map,” only the peak height and mass information are retained from the spectrum view, yielding a cleaner image and enabling molecules of interest with nearly identical molecular weights to be more easily seen. In yet another format, referred to as “gel view,” each mass from the peak view can be converted into a grayscale image based on the height of each peak, resulting in an appearance similar to bands on electrophoretic gels. In yet another format, referred to as “3-D overlays,” several spectra can be overlaid to study subtle changes in relative peak heights. In yet another format, referred to as “difference map view,” two or more spectra can be compared, conveniently highlighting unique molecules of interest which are up- or down-regulated between samples. Profiles (spectra) from any two samples may be compared visually. In yet another format, Spotfire Scatter Plot can be used, wherein molecules of interest that are detected are plotted as a dot in a plot, wherein one axis of the plot represents the apparent molecular weight of the cryptochromes detected and another axis represents the signal intensity of cryptochromes detected. For each sample, molecules of interest that are detected and the amount of molecules present in the sample can be saved in a computer readable medium. This data can then be compared to a control or reference profile or reference value (e.g., a profile or quantity of molecules detected in control, e.g., subjects in whom a Cry-mediated disease or disorder is undetectable).

The data that are generated in the methods disclosed herein can be classified using a pattern recognition process that uses a classification model. In some embodiments, data generated using samples such as “known samples” can then be used to “train” a classification model. A “known sample” is a sample that is pre-classified (e.g., disease or no disease). Data generated using known samples can then be used to “train” a classification model. A “known sample” is a sample that is pre-classified. The data can be used to form the classification model can be referred to as a “training data set”. Once trained, the classification model can recognize patterns in data generated using unknown samples. The classification model can then be used to classify the unknown samples into classes. This can be useful, for example, in predicting whether or not a particular biological sample is associated with a certain biological condition (e.g., diseased vs. non diseased). The training data set that is used to form the classification model may comprise raw data or pre-processed data. In some embodiments, raw data can be obtained directly from time-of-flight spectra or mass spectra, and then may be optionally “pre-processed” in any suitable manner. Pre-processing steps such as these can be used to reduce the amount of data that is used to train the classification model.

Classification models can be formed using any suitable statistical classification (or “learning”) method that attempts to segregate bodies of data into classes based on objective parameters present in the data. Classification methods may be either supervised or unsupervised. Examples of supervised and unsupervised classification processes are described in Jain, “Statistical Pattern Recognition: A Review”, IEEE Transactions on Pattern Analysis and Machine Intelligence, Vol. 22, No. 1, January 2000, which is herein incorporated by reference in its entirety. In supervised classification, training data containing examples of known categories are presented to a learning mechanism, which learns one more sets of relationships that define each of the known classes. New data may then be applied to the learning mechanism, which then classifies the new data using the learned relationships.

Examples of supervised classification processes include linear regression processes (e.g., multiple linear regression (MLR), partial least squares (PLS) regression and principal components regression (PCR)), binary decision trees (e.g., recursive partitioning processes such as CART—classification and regression trees), artificial neural networks such as back propagation networks, discriminant analyses (e.g., Bayesian classifier or Fischer analysis), logistic classifiers, and support vector classifiers (support vector machines). A preferred supervised classification method is a recursive partitioning process (U.S. Patent Application Publication No. 20020138208). Unsupervised classification attempts to learn classifications based on similarities in the training data set, without pre classifying the spectra from which the training data set was derived. Unsupervised learning methods include cluster analyses. A cluster analysis attempts to divide the data into “clusters” or groups that ideally should have members that are very similar to each other, and very dissimilar to members of other clusters. Similarity is then measured using some distance metric, which measures the distance between data items, and clusters together data items that are closer to each other. Clustering techniques include the MacQueen's K-means algorithm and the Kohonen's Self-Organizing Map algorithm. Learning algorithms asserted for use in classifying biological information are described in, for example, International Application Publication No. WO 01/31580 and U.S. Patent Application Publication Nos. 20020193950, 20030004402, and 20030055615. Another classification method involves multivariate predictive models using a non-linear version of Unified Maximum Separability Analysis (“USMA”) classifiers. Details of USMA classifiers are described in U.S. Patent Application Publication No. 20030055615.

Other classification algorithms and formulae include, but are not limited to, Principal Component Analysis (PCA), cross-correlation, factor rotation, Logistic Regression (LogReg), Linear Discriminant Analysis (LDA), Eigengene Linear Discriminant Analysis (ELDA), Random Forest (RF), Recursive Partitioning Tree (RPART), as well as other related decision tree classification techniques, Shrunken Centroids (SC), StepAIC, Kth-Nearest Neighbor, Boosting, Decision Trees, Neural Networks, Bayesian Networks, Support Vector Machines, Leave-One-Out (LOO), 10-Fold cross-validation (10-Fold CV), and Hidden Markov Models, among others.

Detection and correlation of one or more cryptochromes may also be analyzed using any suitable means, including software packages, for example, Applied Maths, GenExplore™, 2-way cluster analysis, principal component analysis, discriminant analysis, self-organizing maps; BioDiscovery, Inc., Los Angeles, Calif. (ImaGene™, special image processing and data extraction software, powered by MatLab®; GeneSight: hierarchical clustering, artificial neural network (SOM), principal component analysis, time series; AutoGene™; CloneTracker™); GeneData AG (Basel, Switzerland); Molecular Pattern Recognition web site at MIT's Whitehead Genome Center; Rosetta Inpharmatics, Kirkland, Wash. Resolver™ Expression Data Analysis System; Scanalytics, Inc., Fairfax, Va. Its MicroArray Suite enables researchers to acquire, visualize, process, and analyze gene expression microarray data; TIGR (The Institute for Genome Research) offers software tools for array analysis. For example, see also Eisen and Brown, (1999) Methods Enzymol. 303: 179-205.

In certain embodiments of the methods of qualifying disease status, the methods further comprise managing or modifying clinical treatment of a subject based on the status of the disease or disorder. For example, if the result of the methods of the present invention is inconclusive or there is reason that confirmation of status is necessary, the physician may order more tests (e.g., CT scans, PET scans, MRI scans, PET-CT scans, X-rays, biopsies, blood tests. Alternatively, if the status indicates that treatment is appropriate, the physician may schedule the subject for treatment. In other instances, the subject may receive therapeutic treatments (such as administration of therapeutic agents (such as, e.g., the compounds of formula I defined herein, either alone or in combination with one or more additional therapeutic agents), either in lieu of, or in addition to, surgery. No further action may be warranted. Furthermore, if the results show that treatment has been successful, a maintenance therapy or no further management may be necessary.

The subject matter disclosed herein also provides for such methods where the cryptochromes are measured again after clinical treatment of a subject. In these cases, the methods are used to monitor the status of a Cry-mediated disease or disorder, e.g., response to treatment, remission of the disease or progression of the disease. The methods can be repeated after each treatment the subject receives, allowing the physician to follow the effectiveness of the course of treatment. If the results show that the treatment is not effective, the course of treatment can be altered accordingly.

The invention provides kits for qualifying disease status and/or detecting or diagnosing disease, wherein the kits can be used to detect one or more cryptochromes. For example, the kits can be used to detect any one or more of the cryptochromes described herein, which the one or more cryptochromes are differentially present in samples of disease subjects and normal subjects. The kits of the invention have many applications. For example, the kits can be used in any one of the methods of the invention described herein, such as, inter alia, to differentiate if a subject has a Cry-mediated disease or disorder or has a negative diagnosis, thus aiding a diagnosis. In another example, the kits can be used to identify compounds that modulate expression of one or more of the cryptochromes, compounds that modulate the activity of one or more cryptochromes (i.e., that affect the ability of one or more cryptochromes to bind to a target such as Per1, Per2, the glucocorticoid receptor (GR), or a promoter sequence recognized by cryptochromes such as the CLOCK-BMAL1 promoter or any other promoter sequence) by using in vitro or in vivo animal models for a Cry-mediated disease or disorder. In another example, the kits can be used to identify binding targets of one or more cryptochrome proteins as defined herein.

Kits of the present invention may include a detection reagent, e.g., nucleic acids that specifically identify one or more cryptochrome nucleic acids by having homologous nucleic acid sequences, such as oligonucleotide sequences, primers, or aptamers, complementary to a portion of the nucleic acids or antibodies to proteins encoded by the nucleic acids packaged together. The oligonucleotides can be fragments of the genes. The oligonucleotides may be single stranded or double stranded. For example the oligonucleotides can be 200, 150, 100, 50, 25, 10 or less nucleotides in length. Alternatively, the detection reagent may be one or more antibodies that specifically or selectively bind to one or more cryptochrome proteins or targets thereof. The kit may contain in separate containers a nucleic acid or antibody (either already bound to a solid matrix or packaged separately with reagents for binding them to the matrix), control formulations (positive and/or negative), and/or a detectable label such as fluorescein, green fluorescent protein, rhodamine, cyanine dyes, Alexa dyes, luciferase, radiolabels, among others. Instructions (e.g., written, tape, VCR, CD-ROM, etc.) for carrying out the assay and for correlation to disease status may be included in the kit.

For example, detection reagents can be immobilized on a solid matrix such as a porous strip to form at least one detection site. The measurement or detection region of the porous strip may include a plurality of sites containing a nucleic acid. A test strip may also contain sites for negative and/or positive controls. Alternatively, control sites can be located on a separate strip from the test strip. Optionally, the different detection sites may contain different amounts of immobilized nucleic acids, e.g., a higher amount in the first detection site and lesser amounts in subsequent sites. Upon the addition of test sample, the number of sites displaying a detectable signal provides a quantitative indication of the amount of cryptochromes present in the sample. The detection sites may be configured in any suitably detectable shape and are typically in the shape of a bar or dot spanning the width of a test strip. The substrate array can be on, e.g., a solid substrate, e.g., a “chip” as described in U.S. Pat. No. 5,744,305. Alternatively, the substrate array can be a solution array, e.g., xMAP (Luminex, Austin, Tex.), Cyvera (Illumina, San Diego, Calif.), CellCard (Vitra Bioscience, Mountain View, Calif.) and Quantum Dots' Mosaic (Invitrogen, Carlsbad, Calif.). The kit may also contain reagents, and/or enzymes for amplifying or isolating sample DNA. The kits may include reagents for real-time PCR, for example, TaqMan probes and/or primers, and enzymes.

In some embodiments, a kit comprises: (a) a substrate comprising an adsorbent thereon, wherein the adsorbent retains or is otherwise suitable for binding a cryptochrome, and (b) instructions to detect the cryptochrome by contacting a sample with the adsorbent and detecting the cryptochrome retained by the adsorbent. In some embodiments, the kit may comprise an eluant (as an alternative or in combination with instructions) or instructions for making an eluant, wherein the combination of the adsorbent and the eluant allows detection of the cryptochrome using gas phase ion spectrometry.

In other embodiments, the kit may comprise a first substrate comprising an adsorbent thereon (e.g., a particle functionalized with an adsorbent) and a second substrate onto which the first substrate can be positioned to form a probe, which may be removed and inserted into machine, such as, e.g., a gas phase ion spectrometer. In other embodiments, the kit may comprise a single substrate, which is in the form of a probe with adsorbents on the substrate that can be removed and inserted into a machine. In yet another embodiment, the kit may further comprise a pre-fractionation spin column (e.g., Cibacron blue agarose column, anti-HSA agarose column, K-30 size exclusion column, Q-anion exchange spin column, single stranded DNA column, lectin column, etc.). In another embodiment, a kit comprises (a) an antibody that specifically binds to one or more cryptochromes; and (b) a detection reagent. An antibody may be, for example, an antibody directed against the gene products of a cryptochrome gene.

Optionally, the kit may further comprise a standard or control information so that the test sample can be compared with the control information standard to determine if the test amount of one or more cryptochromes detected in a sample is a diagnostic amount consistent with a diagnosis of a Cry-mediated disease or disorder.

Although a few variations have been described in detail above, other modifications or additions are possible. In particular, further features and/or variations may be provided in addition to those set forth herein. For example, the implementations described above may be directed to various combinations and subcombinations of the disclosed features and/or combinations and subcombinations of several further features disclosed above. In addition, the logic flow described herein does not require the particular order shown, or sequential order, to achieve desirable results. Other embodiments may be within the scope of the claims.

EXAMPLES Example 1: Reaction Schemes for Synthesis of Compounds

The following reaction schemes, Reaction Scheme I, II, and III, depicts methods of synthesis for compounds of formula I. In the general methods for preparation of the compounds of formula I, the variable R₁, R₂, R₃, R₄, R₅, R₆, R₇, a, and b are as previously defined for a compound of formula I unless otherwise stated. The Reaction Schemes herein described are intended to provide a general description of the methodology employed in the preparation of many of the Examples given. However, it will be evident from the detailed descriptions given in the Experimental section that the modes of preparation employed extend further than the general procedures described herein. In particular, it is noted that the compounds prepared according to the Schemes may be modified further to provide new Examples within the scope of this invention. The reagents and intermediates used in the following examples are either commercially available or can be prepared according to the standard literature procedures by those skilled in the art of organic synthesis.

In the reaction schemes described herein it is to be understood that hydroxyl groups in intermediates useful for preparing compounds of formula I may be protected by conventional groups known to those skilled in the art, as required. For example, intermediates containing a hydroxyl group may be protected as the corresponding tert-butyldimethylsilyl ether and subsequently deprotected by treatment with tetra-n-butylammonium fluoride to provide the free hydroxyl derivative. Suitable protecting groups and methods for their removal are illustrated in “Protective Groups in Organic Synthesis”, 3^(rd) Ed., T. W. Greene and P. G. M. Wuts (Wiley & Sons, 1999).

¹H Nuclear magnetic resonance (NMR) spectra were in all cases consistent with the proposed structures. Characteristic chemical shifts (6) are given in parts-per-million downfield from tetramethylsilane using conventional abbreviations for designation of major peaks: e.g. s, singlet; d, doublet; t, triplet; q, quartet; m, multiplet; br, broad. The mass spectra (m/z) were recorded using either electrospray ionization (ESI) or atmospheric pressure chemical ionization (APCI). Where thin layer chromatography (TLC) has been used it refers to silica gel TLC using silica gel 60 F₂₅₄ plates, R_(f) is the distance traveled by a compound divided by the distance traveled by the solvent front on a TLC plate. HPLC refers to high performance liquid chromatography.

Specific assays useful for evaluating the compounds of formula I include the Per2 Assay for Evaluating the Potency of Test Compounds and the Cry1 Assay for Evaluating the Target of Test Compounds, as described below.

Example 3: Per2 Assay for Evaluating the Potency of Test Compounds

Compounds were screened by using a high-throughput circadian assay system as previously described in Zhang, E. E. et al. Cell, 2009, 139, 199-210. In brief, stable U2OS reporter cells harboring Per2-dLuc were plated at a density of 8,000 cells/well in Corning 96-well, solid white, flat bottom, TC-treated microplates (Corning®), and incubated for 24 hours at 37° C. in the presence of 5% CO₂. The cells were then synchronized by serum shock by media exchange to a minimal explant media (10 mM HEPES (pH 7.0), 2% B27, 1×PSG (Invitrogen®), and 1.0 mM beetle luciferin (Promega®)) followed by the addition of the compounds of formula I dissolved in dimethylsulfoxide (0.5% final dimethylsulfoxide concentration). Gene expression was monitored by measuring luminescence (Tecan® M200) over 4-5 days at 35° C. The period, amplitude, and phase of the associated circadian rhythms were determined using Multicycle™ software (Actimetrics, Inc).

Example 4: Cry1 Assay for Evaluating the Target of Test Compounds

HEK293 cells (2.5×10⁶ cells) were reverse transfected on 6-well plates with 2 μg expression vector by Lipofectamine 2000. After 28 hours, the cells were collected in ice-cold PBS and re-suspended in 100 L of incubation buffer (50 mM Tris, 50 mM NaCl, 2 mM EDTA, 10% glycerol, 1 mM DTT, Complete Protease Inhibitor Cocktail, Phosphatase Inhibitor Cocktail 1 and 3; pH 8.0). The mixture was supplemented with NP-40 (final 1%) and incubated on ice for 15 mins, followed by centrifugation (16,000×g) at 4° C. for 10 mins. The supernatant was used for assays. Expression vectors for C-terminally 3× Flag-tagged mCRY1 were based on p3×FLAG-CMV-14 (Sigma).

Cry1::Luc or Luc reporter HEK293 cells (1.0×10⁴ cells) were plated onto 384-well white solid-bottom plates at 50 μL per well. After 24 hours, 500 nl of the compound (final 1% dimethylsulfoxide) was applied to the medium. After 24 hours, the medium was supplemented with luciferin (final 1 mM) and HEPES-NaOH (pH7.2; final 10 mM), and the luminescence was recorded every 7.5 min for 1 hour with a microplate reader. The luminescence intensity parameter was calculated by averaging the intensity during the experiment. The first data point was excluded from the analysis because of transient luminescence changes. Cry::Luc intensity is normalized to Luc intensity to provide final EC₅₀ values. EC₅₀ values of the compounds of formula I were calculated using Graphpad™ (Prism®).

The following table provides Cry1 EC₅₀ data for the specified Examples. The EC_(50s) are reported as micromolar concentration.

Example 5: Transient Assay for Steady-State CRY1 Protein Stabilization

HEK293 cells are transfected in 24 well plates with a mammalian expression vector (0.5 μg/well) containing a cDNA encoding full-length CRY1 with a C-terminally-encoded MycDDK tag (Origene) or FLAG-tag (Sigma) using Lipofectamine 2000 or an equivalent reagent. After 24 hours the cells are treated with test compounds with up to a final concentration of 1% DMSO. After a further 24 hours, the cells are lysed in RIPA buffer (150 mM NaCl, 1.0% IGEPAL® CA-630 (or NP-40), 0.5% sodium deoxycholate, 0.1% SDS, and 50 mM Tris, pH 8.0) containing protease inhibitor cocktail. Protein gel sample buffer is added to equivalent amounts of each sample and they are separated on a SDS-polyacrylamide gel and electrophoretically transferred to a PVDF membrane. Tagged proteins are detected with a tag-directed primary antibody and a secondary antibody conjugated to HRP. Tagged CRY1 protein is revealed by chemi-luminescence with ECL+ or other similar reagent and recorded with a digital camera as a RAW file. Photoshop and ImageJ software are employed to quantitate individual bands. The amount of tagged CRY1 protein can be compared to total protein in the loaded sample or to a subsequently detected internal control protein such as GAPDH. The relative amount of tagged CRY1 protein can be determined by comparing compound-treated cell samples to DMSO-treated cell samples. Increases in tagged CRY1 protein compared to control samples indicate that the compound increases CRY1 stability. Decreases in tagged CRY1 protein compared to control samples indicate that the compound decreases CRY1 stability. The assay described supra can be readily modified and optimized by those skilled in the art to measure or determine endogenous protein levels of any of the proteins involved in circadian rhythm and/or CRY-regulated pathways, for example, Cry2, Per1, Per2, CLOCK, BMAL1, TIM protein, or VEGF.

Example 6: Stable Cell Line Assay for Steady-State CRY1 Protein Stabilization

A stable cell line expressing a tagged CRY1 protein is treated with test compounds for 24 hours in up to 1% DMSO. After a further 24 hours, the cells are lysed in RIPA buffer (150 mM NaCl, 1.0% IGEPAL® CA-630 (or NP-40), 0.5% sodium deoxycholate, 0.1% SDS, and 50 mM Tris, pH 8.0) containing protease inhibitor cocktail. SDS-containing protein gel sample buffer is added to equivalent amounts of each sample and they are separated on a SDS-polyacrylamide gel and electrophoretically transferred to a PVDF membrane. Tagged proteins are detected with a tag-directed primary antibody and a secondary antibody conjugated to HRP. Tagged CRY1 protein is detected by chemi-luminescence with ECL+ or other similar reagent and recorded with a digital camera as a RAW file. Photoshop and ImageJ software are employed to quantitate individual bands. The amount of tagged CRY1 protein can be compared to total protein in the loaded sample or to a subsequently detected internal control protein such as GAPDH. The relative amount of tagged CRY1 protein can be determined by comparing compound-treated cell samples to control or DMSO-treated cell samples. Increases in tagged CRY1 protein compared to control samples indicate that the compound increases CRY1 stability. Decreases in tagged CRY1 protein compared to control samples indicate that the compound decreases CRY1 stability. The assay described supra can be readily modified and optimized by those skilled in the art to measure or determine endogenous protein levels of any of the proteins involved in circadian rhythm and/or CRY-regulated pathways, for example, Cry2, Per1, Per2, CLOCK, BMAL1, TIM protein, or VEGF.

Example 7: Determination of Half-Life of CRY1-Tagged Protein

Transiently transfected HEK293 cells or stable cell lines expressing a tagged-CRY1 protein are exposed to test compounds for 24 hours and then exposed to cycloheximide (1 μg/ml). The cells are lysed in RIPA buffer after incubating from 15 min to 6 hours. SDS-containing protein gel sample buffer is added to equivalent amounts of each sample and they are separated on a SDS-polyacrylamide gel and electrophoretically transferred to a PVDF membrane. Tagged proteins are detected with a tag-directed primary antibody and a secondary antibody conjugated to HRP. Tagged CRY1 protein is detected by chemi-luminescence with ECL+ OR OTHER SIMILAR REAGENT and recorded with a digital camera as a RAW file. Photoshop and ImageJ software are employed to quantitate individual bands. The amount of tagged CRY1 protein can be compared to total protein in the loaded sample or to a subsequently detected internal control protein such as GAPDH. The rate of the decline in tagged CRY1 protein abundance can be compared between test compound-treated samples and control or DMSO-treated samples. A faster rate of decline of tagged CRY1 protein in compound-treated samples compared to control samples indicates that the compound decreases CRY1 stability. A slower rate of decline of tagged CRY1 protein in compound-treated samples compared to control samples indicates that the compound increases CRY1 stability. The assay described supra can be readily modified and optimized by those skilled in the art to measure or determine the half-life of any of the proteins involved in circadian rhythm and/or CRY-regulated pathways, for example, Cry2, Per1, Per2, CLOCK, BMAL1, TIM protein, or VEGF.

Example 8: Endogenous CRY Protein Assay

Cells or tissues are exposed to test compounds or vehicle for 2 hours to 4 days prior to harvest and homogenization in RIPA buffer containing protease inhibitor cocktail. SDS-containing protein gel sample buffer is added to equivalent amounts of each sample and they are separated on a SDS-polyacrylamide gel and electrophoretically transferred to a PVDF membrane. The amounts of endogenous proteins are detected with specific antibodies directed to CRY proteins and a secondary antibody conjugated to HRP. CRY protein is revealed by chemi-luminescence with ECL+ or other similar reagent and recorded with a digital camera as a RAW file. Photoshop and ImageJ software are employed to quantitate individual bands. The amount of tagged CRY1 protein can be compared to total protein in the loaded sample or to a subsequently detected internal control protein such as GAPDH. The relative amount of CRY protein can be determined by comparing compound-treated cell or tissue samples to control, or DMSO-treated, cell or tissue samples. Increases in CRY protein compared to control samples indicate that the compound increases CRY stability. Decreases in CRY protein compared to control samples indicate that the compound decreases CRY stability. The assay described supra can be readily modified and optimized by those skilled in the art to measure or determine endogenous protein levels of any of the proteins involved in circadian rhythm and/or CRY-regulated pathways, for example, Cry2, Per1, Per2, CLOCK, BMAL1, TIM protein, or VEGF.
